Abstract
The results of studies of the characteristics of the biochemical composition of acutifolia in the conditions of a large industrial center of Naberezhnye Chelny (Republic of Tatarstan) are presented. Under condi-tions of intense technogenic load, the maple has a higher ascorbate oxidase activity at the initial stages of active vegetation and lower at the end of the vegetation. The content of ascorbic acid decreases during the growing season in man-made stands. Under conditions of a high content of pollutants in the air, acutifolia maple was distinguished by an increase in the activity of polyphenol oxidase as compared to control plantings. An increase in the activity of polyphenol oxidase is accompanied by a decrease in the content of tannins. In maple acutifolia, under the conditions of the most intense load of the main plantations, in July the peroxidase activity in the leaves is lower than in the ZAK plantations, and in August it is higher than in the control.
